Provide for a birth day tax credit for the birth of a child

This bill creates a new refundable tax credit for Montana residents who have a child born in the year they file their taxes, providing up to $3,000 to help offset state and federal income taxes. The credit amount is reduced for higher-income families, with phase-out thresholds of $60,000 for most filers and $120,000 for married couples filing jointly, and it requires parents to report the child's birth information on their tax return. Additionally, the bill adds this new credit to a list of other tax incentives that must be reviewed by the revenue interim committee every eight years to assess their effectiveness and impact on taxpayer decisions.
